OPTICAL SENSOR, OPTICAL SENSOR SYSTEM, AND ENDOSCOPE

摘要

At least a portion of a characteristic variation section (201) is disposed at a position differing in the peripheral direction of an optical sensor (10) with respect to at least a portion of a characteristic variation section (203). Also, at least a portion of the characteristic variation section (201) is disposed at a position differing in the axial direction of the optical sensor (10) with respect to at least a portion of the characteristic variation section (203).
